SPECIFICATION forming part of Letters Patent `No. 283,054, dated August 14, 1883.

To all whom t may concern:

Be it known that we, WILLIAM M. WOOD and WILLIAM L. BAILIE, both citizens of the `United States, residing at .Washingtom Dis trict of Columbia, have invented certain new and useful Improvements in Ice Machines; and we do hereby declare thepfollowing to` `be a full, clear, and exact description of the inventi'on, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates to improvements in processes of and apparatus for the manufacture of ice or producing coldair; and the obj ect is i i I i working ofthe vessel, andthereby leakage of `to produce ice or cold air in a more economical manner than has hitherto been done, and to furnish machinery that will be less complicated, take up less space, and that is especially adapted for vessels by placing all the/main parts 011 a bed-plate made in one piece, so that the different joints are `not affected by the ammonia vapor is prevented and a more perfeet machine is produced. y Our invention consists in the construction Like letters indicate like parts in the differ! ent figures of the drawings, in which Figure l represents a vertical section on line m x of Fig. 3, showing the condensing-coil and the refrigeratingcoil, Src. Fig. 2 is an end Fig. 3 is a plan view of the same. Fig. 4 is a detail view of the refrigerating-box. Fig. 5 is a vertical section of the compressing-pump.

` In the drawings, A is the bed-plate, made sufficiently strong to resist the ordinary strains or workings of avessel, and is preferably made of one piece of Inetal. To this bed-plateware bolted the refrigerating-coil B, the condens-` ing-coil C, the compressing-pump D, the circulating-pumps E F, `the receiver G,for the liquid'ammonia, and a suitable engine, I. The

refrigerating-coil is surrounded by a casing,

" b, filled with cork or other suitable non-conducting material, and is connected by a pipe, b,with the lower end of the receiver GQ. The

liquid ammonia is carried up the pipe b until it reaches a regulating-valve, c. l At this point and, after performing its work of condensation of the ammoniacal gas, it is discharged through a pipe, c2, at the top of the casing c. The pump Fpreceives its source of supply of refrigerating medium'from the top of the refrigating-box I-I. From then ce it is forced through the casing b by a pipe, f, at the bottom of refrigerating-coil B, and traverses the coil, there by becoming deprived of its heat, is forced through an opening at the top of casing b, and is returned to the refrigerating-box, thus acting in a continuous cycle. ment of outlet and inlet itis impossible to overflow the refrigeratingsbox, or, if the pump F should cease to draw from the box, the supply to the box will also cease.

In case of very large machines the bed-plate may be made in pieces, but must be then bolt ed` or jointed together so iirmly as to form virtually one piece.

frigerating medium, into which the boxes M` project. In said boxes the cakes of ice are formed, and they are detachably'secured to said plate k by suitable thumb-screws, Z, which pass through the annular flange m, attached to the boxes. VA wooden cover, n, is then placed on the boxes. box H and bottom of the coil B,while a pipe, p, connects with the bottom of the box Hand top of the coil B to form a complete circulation for the refrigerating medium.

If it is desired to cool the air, pipes may be By this arrange" The refrigerating-box I-I consists of anouter A pipe, o, connects with the top of the it is compressed and forced IOOf arranged inthe rooms to be cooled in the usual well-known manner.

It will be readily perceived that our ice-ma chine can be made of any desired size and capacity; but in all cases it will occupy a much smaller space in proportion to capacity than any other ice-machine. It-is simple in construction. No leakage of ammonia can possibly occur, as there are no joints which cannot be properly packed. The joints will not be affected by the working of the Vessel, as all .the parts are on a solid bed-plate. The parts are not liable to get out of order, as they are very simple in construction. All the parts are easily accessible in case of needed repairs or replacement of any parts, and it can be-furnished at a very small expense.

Having thus described our invention, what we claim, and'desire to secure by Letters Patent, is

l. In an ice-machine, the bed-plate A, cast in onepiece, in combination with the refrigerating-coil, condensing-coil, receiver, circulating-pumps, and a compressing-pump, all constructed and arranged substantially as andfor the purpose specified.

2. In an ice-machine, the combination of the compressing-pump, constructed as shown, with a pipe, c, condensing-coill C, pipe d, and a receiver, G, all arranged, substantially as s et forth, on a bed-plate cast in one piece.

3. The combination ofthe compressing-pump D, constructed as shown, with the receiver G, pipe b',regulating-valve a, pipevb, refrigerating-coil B, pipe b, pipe 0, condensing-coil C, and pipe d, all arranged in'the manner and for the purpose specified.

4J The combination of a bed-plate, A, a refrigerating-coil, B, a condensing-coil, C, a coinpressing-pump, D, circulating` pumps E F, a receiver, G, and an engine, all arranged'on said bed-plate, substantially as specified.

5. The combination of a refrigerating-coil, B, and a pump, F,with a refrigerating-box, H, pipeo, connecting the top ofcasing b and the bottom of' said box H, and apipe, p, connecting the bottom of casing b and the top of said boX H to act as a cycle, substantially as and for the purpose specified.

6. ln an ice-machine, the combination of the condensin gcoil G and casing c with a pump, E, a pipe, c, communicating with the bottom of'said casing, and pipe, ci, for discharging the water at the top of said` casing, substantially as set forth.

7. The process herein described, consisting` in drawing the liquid ammonia from a receiver, evaporating it at the upper part of a refrigerating-coil, drawing it to a compressing-pump, then forcing it into a condensing-coil and returning the liqueed ammonia to the receiver, substantially as specified.

S. The process herein described, consisting in forcing water by means of a pump into the bottom of a casing surrounding the condensing-coil of an ice-machine' and discharging it at the top, while at the same time drawing a refrigerating medium from the top of a refrigerating-boX, forcing it in at the bottom of a casing surrounding a refrigerating-coil, and after traversing said coil returning it to the bottom of the refrigerating-'bo-X, substantially as set forth.

9. The method herein described of drawing a refrigerating medium from the top of a refrigerating-box, forcing it in at the bottom of acasing surrounding a refrigerating-coil, and after traversing said coil, thereby depriving it of its heat, returning it to the bottom of a refrigerating-coil.

ln testimony whereof we affix our signatures in presence of two witnesses. i
